In a circuit such as the one attached, what difference does the value of VR1 make? Would a 5k pot perform any differently from a 50k or 100k?
Thanks.

I am connecting the audio output from my TV to an FM transmitter so that I can listen to the TV with the FM function on my MP3 player and not disturb my wife. I have not measured the output from the TV, but the audio received on the FM signal is quite distorted. Using a lower level audio source (another MP3 player), the audio on the FM signal sounds good. So, it seems that the audio output from the TV is quite high.Does your input signal have enough "muscle" to drive 5k ohms without distortion?
The stereo outputs from the TV that I am measuring are a couple (R and L) of RCA jacks, which are not affected by the volume control or the mute switch on the remote. I don't actually know what their intended purpose is.The TV output is probably designed to drive a low impedance headset.
Hence any low resistance voltage divider or pot should work.
Do they need to be mylar film or will ceramic work just as well?In North America C1 and C4 should be 1500pF.
